STANDING VALVE.

Abpuoatm mea December 31,1921. serial no. 526,304.

To all whom it 'may concer/n.'

Be it known that I, CoRwIN M. BERLIEN, citizenA of the United States, residing at -Burkburnett, in the county of Wichita vand State of Texas, have invented new and useful Improvements in Standing Valves, of which the following is a specification.

This invention relates to improvements in oil well apparatus, the general object of l@ the invention being to provide means for so arranging the standing valve that it will be free from obstructions 'and sand will be prevented from reaching the cups in the Working barrel so that the .parts will last l5 for a long time and the maximum production of oil will be secured ata minimum cost.

This invention also consists incertain other features of construction and in the 2@ combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and s ecically pointed o ut in the appended c aim. Y

ln describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several viewsfand in which:-

tion of an oil well showing myunvention.

in use. l

Figures 2 and 3 are detail views of the invention.

'ln these views a casting lis shown having a central longitudinal bore 3 which merges into a large screw threaded socketl 2 at each end. A perforated tubing d is threaded into the lower socket 2 and this tubing iscon- 0 nected with the anchor tubing 5. A smaller tubingV 6 is threaded into the lower socket 3 and this tubing is the gas anchor. The tubing 6 passes through the tubin d.' A. pipe 7 has its lower end screw threa ed into the upper socket 2 and this pipe supports the workingV barrel 8. A smaller pipe 9 has its lower end-screw threaded into the upper socket 3 and the upper end of this pipe supports ythe standing valve 10, the pipes 7 and 9 forming a chamber 1l into which sand and sediment will settle from the oil passing through the standing valve. This will prevent sand from reaching the cups in the working barrel and injuring them so that the improved device will work efectually for a much longer time than where the standing valve is connected directly'with the perforated tubing. The oil will pass through the perforated tubing so that it will be strained thereby before it passes into the tube 6. g

-It is thought from`they foregoing description that the advantages and novel features of my invention will be readily apparent.

ll. desire it to be understood that I may make changes in theconstruction and in the combinationand arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What ll claim is In combination, a well casing joint for standing valves consisting of a casting having a central bore threaded at each end and provided between the threaded portions with an internal flange, said ange being of such thickness as to leave an opening of the same diameter as the internal diameter of suction and valve pipes iitting the threaded portions of the bore, said casting further having an internally threaded flange at each end adapted for connecting a well casing pipe, an im-f perforate well casing pipe screwed into the upper ange of the casting, a perforate well casing pipe screwed into the lower end ot the casting, a standing valve pipe screwed butted against said flange, and a suction pipe screwed into the lower end of the casting bore and likewise butting against said flange whereb a smooth and unobstructed passage of uni erm diameter throughout extends through the suction pipe, the casting and standmg valve pipe, said casting being ot uniform dimensions at each end.

linto the upper end of the casting bore and lin testimony whereof ll ax my signature.
